Award availability from LAX to NRT is open on April 14, 2026, with plenty of Premium Economy seats bookable through United MileagePlus. At 65,000 miles with minimal taxes, this is a worthwhile option for families planning a spring trip to Japan when the tail end of cherry blossom season may still be in play.
For context, this route typically prices at around 80,000 miles for Premium Economy awards. The current availability saves you roughly 15,000 miles per ticket—meaningful savings if you're booking for multiple family members.
Premium Economy offers a nice middle ground for long transpacific flights: more legroom, better recline, and improved meal service compared to standard economy, without the points outlay required for business class. For a 12-hour flight with kids, the extra comfort can make a real difference.
One practical note: April is peak travel season for Japan, so if these dates work for your schedule, it's worth locking in sooner rather than later. Award space during spring tends to disappear as the season approaches.
